MOTOR TO CONTROL AUTOMATICALLY A SUBSCRIBER/S TELEPHONE FOR VARIEDSERVICE.

Specification of Letters Patent. Patented Sept. 19, 1916,

Application filed October 5, 1915. Serial No. 54,138.

To all whom it may concern:

Be it known that I, EDWIN V. M. BRnN- NAN, a citizen of the UnitedStates, residing at the city of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Motors to Control Automatically a SubscribersTelephone for Varied Service, of which the following is a specification.

My invention relates to a motor to establish and control automatically atelephone circuit from a subscribers telephone through a central stationwith another telephone for intercommunication, recording a call, tolight and extinguish lights at distant points by telephone connection,to register predetermined calls of different subscribers telephones onthe operated telephone, as well as phonographically calls through thesubscribers telephone actuated and controlled by the motor set in actionby a rolling contact actuated by the clapper of a central stationcircuit bell to establish the circuit of the subscribers telephonethrough the central station with the telephone in which requiredconnection is desired.

My invention in such connection relates to the general structuralarrangement of the motor and accessories adapted to be brought intorelation therewith and operated thereby and to the automatic operationof the motor for bringing the subscribers instrument into and out ofcircuit through the central station with the particular subscriberstelephone desired for certain or all of the defined purposes.

The nature, scope and characteristic features of my present inventionwill be more fully'understood-from the following description taken inconnection with the accompanying drawings, forming part hereof, in whichFigure 1, is a diagrammatic View of a 2, is a front elevational View ofthe motor, showing the same in engagement with the receiver-arm of thesubscribers telephone. Fig. 3, is a plan view of Fig. 2. Fig. 4;, is avertical sectional view through the casing of the motor, showing theoperating mechanism and registering device operated by the motor and atiming device' shown in broken section. Fig. 5, is a detail View of anadjustable cushioned saddle adapted to be brought up against thereceiver-arm'of the telephone in lifting the same by the action of themotor. Fig. 6, is a view partly in section and partly in frontelevation, a modified form, in this instance a double rolling contactarranged to be actuated either way by the clapper of a central stationbell; and Fig. 7, is a transverse section on the line a", w, of Fig. 6,showing a means to angularly adjust the casing as the movable contactsshift with respect to each other and as operated by the vibrations ofthe bell clapper, for example in the manner as shown in Fig. 6.

Referring to the drawings a, represents the motor mounted in a casing a.The shaft a of the motor carries a pinion a meshing with a largegear-wheel a This gear-wheel carried on a cross-shaft a has fixedthereto a cam a, for controlling the up and down movements of a longleverarm a arranged lengthwise of the casing a and pivoted at one end inthe said casing thereto and carrying at the free end thereof and beyondthe said casing, a. padded saddle a adjustably supported in requiredposition by means of a tightening nut a In the casing a, as shown inFig. 4, is arranged an adjustable contact a so that by the lifting ofthe said lever-arm a, in a manner to be hereinafter more fully explainedpositive contact is established with said arm. In the casing a is alsomounted any well known type of registering device a, the movement of thelever-arm a, shift ing the numeralsof the same, so that any call of thetelephone may thus at once he observed through the opening in the faceof the said device at the subscribers telephone. Mounted on the shaft ois a phonograph disk a", with .a reproducer a, and a horn a, which maybe brought into the path of the transmitter b of the telephone, forexample, as clearly shown in Figs. 2 and 3. This telephone is providedwith a receiver 6 and forked arm 6 engaging the same which is adapted tobe brought into contact with the cushioned saddle a, for placing thereceiver thereby in a position to be automatically lifted by the motora, in a manner to be hereinafter more fully explained.

c, is a lighting system, showing the generator 0 and a switch 0 with achain 0 connected with one terminal of said switch, for operating thesame. The chain 0 is adapted to engage a hook a, of the leverarm a",operated by the motor a, as clearly shown in Fig. 1.

The foregoing isone of the applications in which the motor a, can beemployed in conjunction with a telephone system, to controlautomatically the making and breaking of connection between subscriberstelephones through a central station exchange,

' not shown, and in which also the lighting and the extinguishing oflamps of a, plant can be controlled thereby at predetermined times bythe use of the timing device d, controlled through the said motor a, bythe operation of a subscribers telephone in circuit with said motor aswill be hereinafter more fully explained.

Adjacent to the bell-box e, in the circuit of the central stationexchange, not shown, is provideda clapper 6 for tapping the bell orbells e thereof, as clearly shown in Figs. 1 and 6. In close proximityto the clapper 6 is arranged pivotally supported, a tube 0 Fig. 1, withinternal track-ways e, e, suitably insulated from the said tube for thereception of a ball or balls 0 as clearly shown in Figs. 1 and 6. Theball normally rests in one extremity of the tube, beyond the track-waysprovided therein. The vibration of the clapper e drives the ball 6 fromits normal position onto the trackway '6 e, to thereby establish acircuit by the lines 10, 11, from the source of energy 12 and line 13,to the positive contact a and by a branch line 14 to the timing device11,

land by the line 15, to the lever-arm a and by the line 11 to the motora, and by the line 16, to the binding post 03 of the said timing deviced. The timing device (1, "consists of a series of 12 separate ordistinct sectional insulated. cont-acts d as clearly illustrated inFig. 1. This device is provided with plugs (Z in the series of sectionsd This timing device 'd, is provided with hands d d operativelycontrolled by a suitable clock-work mechanism, not shown. Thearrangement of this timing device provided with the plugs LP, is such asthat at predetermined different hours the subscribers telephone can beactuated to establish automatically through the central station exchangecommunication with some other subscribers telephone or telephones orfailure to establish such connection and of that fact being known by theexposure of a certain numeral in the opening of said registering devicea.

In establishing a circuit through the telephone, the exchange bell callis actuated to cause the clapper e and it in turn to drive the ball 6onto the trackways 6, 6 of the adjustable tube 6 so as thereby toestablish the circuit 10 and 11, and branches thereof, to and throughthe motor a, to cause it to be set inaction and in turn the longitudinallever arm a, to be brought into engagement with the contact a, when theball 0 by this time, will by gravity fall back into the extreme end ofthe tube 6 for example, into the position as shown in Fig. 1. Thecontact being established as just described, the motor continues tooperate until the telephone receiver forked arm is lifted to establishintercommunication of such telephone through the exchange with any otherparticular subscribers telephone desired, or the fact it cannot be hadby reason of being busy or not answering, which will be registered onthe device a, through lifting of the said lever-arm a. It can be soarranged as shown, so that the phonograph by having recorded the call,will when the telephone is again operated call this particular number ofthe telephone that was desiredv or that could not be had and the factgiven through the transmitter of said subscribers telephone. By placingthe chain 0 in engagement with the hook a. of the lever-arm (1., andplugging in on the timing device d, the particular hour to light orextinguish a lamp or lamps of a distant lighting plant, in the automaticoperation of the telephone receiver, by the motor a, can be readilyaccomplished. The plug being arranged in the branch circuit 14, from thesource of energy for this purpose, as will be readily understood fromFig. 1.

The important feature of my said invention is to automatically connectup the receiver-arm of a telephone with a motor to enable when theoflice force is absent to permit a person to call that telephone and tohave the call register or to phonographically record the same so that inagain 0 erating the telephone the call will be t en given to theoperator or through the registering device, the call noticeable by thechange of numeral exposed through the face of the said device a. It canalso be employed equally well for the switching in of the lamps of adistant lighting plant by the action of the said timing device operatingin conjunction with the said motor to raise the receiver-arm so as toestablish automatically the circuit at some predetermined hour' ormoment of time. Each subscribers telephone it is to be understood mustbe provided with such a motor for the defined purpose.
